Pruning

The typical habit of this tree is to grow lots of branches and twigs, which should be pinched and pruned regularly to keep guava bonsai in the desired shape. Also, remove suckers as soon as you notice them.

Wiring

Another method to influence the shape of a guava bonsai is wiring. Its branches are rigid when matured and extremely easy to break. That’s why it is best to wire it when branches are young, using a copper wire. Wiring is best done in winter months and after the defoliation.

Bonsai Guava Tree Care Information

Fertilizer

Guava bonsai needs fertilizer during the growing season from spring to fall (autumn) using an organic balanced liquid fertilizer. Fertilizing should be suspended in winter or when the tree is not growing or if it is recently repotted.

Repotting

To prevent the tree from being pot-bound, regular repotting is crucial. The guava tree should be repotted in every 2 years in the spring. When repotting, pruned the roots so that the plant can fit in the pot. This also stimulates a better root system. Prune up to 1/4 root mass.

Overwintering

In colder zones, it should be brought indoors since the Guava is a tropical plant. The temperature should be around 55-60 degrees Fahrenheit. At the temperature below 50 degree Fahrenheit the tree starts to loose leaves.

It must be ensured that tree is overwintered in particularly the brightest spot possible, away from cold drafts.

Pests and Diseases Prevention

The best protection against diseases is a careful maintenance and regular inspection of guava tree bonsai. Although, guava is a tough plant but it can be attacked by common pests that are easily repelled by the use of organic pesticides.
